A couple things that might be problematic:
Check if your bootloader is using disklabels rather than hard partitions for the
filesystems. Your fdisk output does not appear to use labels but you can verify
this. If not, changing the partition number won't affect what the partition gets
mounted as.
Re-writing a partition map where you have modified partition sizes can zap
everything on the disk. (!!!)
BTW, have you considered using LVM instead? It's very easy to configure and helps
avoid this problem in the future. I put up some notes at
http://www.digitalhermit.com/linux/lvm . In your case you could remake the hda5
partition into an LVM partition then suballocate it and grow the fs later. That
you're using ReiserFS is also helpful, since you can resize on the fly in the
future.
